This inventionrelates to agricultural appliances and has more particular-reference I to anew type of ijmp'lement which is espeor any suitable draft appliance, the same be} ing especially constructed to move along the cially adapted for cultivating "and pulverizing SO11 1n the plantrows, x

has a matter of common knowledge that it is diflicult for young plantsto thrive when rows for loosening and pulverijzing the soil to render it more susceptible 1 to. maturing y'oungplants. i

Briefly stated, the appliance comprises a frame which is constructed to be attached to l for rotation. These wheels are so arranged as to permit them to move" d rectly over the I rows or on oppositeisides and close to the an appropriate draft appliance, :this frame carrying adependlng standard on wh ch one or more spike equipped wheels are mounted planted seeds The fraine is associatedwith an ad ustable ground engag ng runner structure, thereby making an ldealcornbinatlonof I partsfor fulfilling thefrequirements of an w Inthe drawings i invention of thisclass in a highly satisfactory nanner. I v v "The particular details will become more readily apparent from the following description and drawlngs', r

As shown better in Figures 1 and the,

main frame is designated generally hy the reference characterS and comprises "a pair of rearwardly conver ing longitudinal bar members 9. These are connected at their for-' ward end to a cross piece 10, making some- 'what of a triangular supporting frame. At

the-end of the part 10 are extensions which define pintles Atthe pointconvergence of the bars 9' is'a, depending standard 12 on the lower end of which-we find outstanding stub axles 13: and- 14', respectively; as" shown better'in Figure 3. Incidentally there may be a pair of wheels or a group of four, six

or eight wheels as desired on the inner end portions of the. stub axles are spacing and bearing washers 17 which cooperate with-the hub portions ofthe wheels. The wheels it' will be noted, are ofthe spoke equipped type and havering like rims 18.. this connection *it will be observe'dthatf the .riins are I formed with screwthreaded holes to accoin- 1 modate the correspondingly threaded shanks 19 of the pointedf'detachable.groun diengaging andpul'verizing calks 2031 also invite attention to thesupplementalwashers 21 on i the extended end. portions of -the axles,

These are to permit" the distances between the wheel sf15 and 1 6'to be regulated Iinention too that the axles 1 3 and 14' are arranged at angles with respect-to each other as to causes the forward or front'portions of the wheels to, converge into close spaced prox-' imityas w as to n y st addletthe W-- r ';V

In K V i I 1 other words. each runner includes an u standing front portion 24, a,-hor1zontal ground engaging's1ide25'and an upstandf Y ing forwardly and upwardly inclined rear portion 26. The upper ends of the forward portion 24 terminate in knuckles 27 which are hingedlymounted on the aforesaid pin. tles 11; In addition I provide an adjusting connection between the rear end portion of g the runner structure and the main frame '8,

i This comprises link connectors28which are fastened to a pivotally mounted lever 29. This lever is mounted onthe rear portion of the frame 8 and provided witha pawl 30 for selected engagement with the keeper notches or seats inthe relatively stationary segments 31 on the frame 8. This allows the runner.

structure to be elevated or' lowered to regulate the depth of penetration of the calksQO;

I call attention to the factthat the construction of the ground engaging vwheels may be varied to the extent of increasing or decreasing the diameter thereofas-well'as increasing the size and shape ofthe ground ,engagingcalksh For instance, as shown in Figure 5'the calks are somewhat fiat in configuration and in Figure 6 they are in the form ofrelatively large conicalspurs.

the wheels whereby-they may be arranged in A converging pairs to provide the desired distanceibetween the wheels for'proper pulverizingand cultivating of the soil'when moving the device alongthe rows." The runners obviously straddle 'therow and the rotating wheelsstraddle on the top of the'row. It is thought. however, that persons skilled in the art to which the inventionrelates'will be able to obtain a clear understandingof the construction, operation; features'and' advantages of the invention after considering the description in connection with-the drawings. Therefore, a more lengthydesc ription is re.- garded as unnecessary. 7 'Minor chan ges in sh'apei size, re-arrange ment of details coming within the'field of invention claimed may be resorted to in "ac- I tual practice-if desired;
